Insects

The guide features 29 species in the insect class. Each profile answers the most-searched questions first.

What are insects?

Insects are six-legged invertebrates with a hard external skeleton (exoskeleton) and a body divided into three parts: head, thorax, and abdomen. Most have antennae, and many have wings — insects were the first animals to evolve flight. With millions of species, they are the most diverse group of animals on Earth and act as essential pollinators, decomposers, and food-web links.
